Can @RequestParam be used on non GET requests?

Question

Spring documentation says:

Use the @RequestParam annotation to bind request parameters to a method parameter in your controller.

AFA

Answer 1

It works with posts too. Can you post your method body and you html?

Answer 2

Instead of @RequestParam which binds to a single form value, you can use @ModelAttribute annotation and bind to the whole object. But it should be used in conjunction with form or bind Spring's JSTL.

Example: - controller that calls JSP-page, it should add objects to a Model:

@RequestMapping(value="/uploadForm", method=RequestMethod.GET)

public String showUploadForm(Model model) {

Artist artist = new Artist();
Track track = new Track();

model.addAttribute("artist", artist);
model.addAttribute("track", track);


return "uploadForm";

}

• JSP might look something like that:

Track Title *:

• Controller that processes form submission;

  @RequestMapping(value="/uploadToServer", method=RequestMethod.POST)

  public String uploadToServer(@ModelAttribute("artist") Artist artist, @ModelAttribute("track") Track track) { .... }

Here I found a good explanation of using @ModelAttribute annotation - krams915.blogspot.ca

Answer 3

Yes it works perfectly with post method too. you can mention the method attribute of @RequestParam as RequestMethod=POST. Here is the code snippet

@RequestMapping(value="/register",method = RequestMethod.POST)

public void doRegister
(

    @RequestParam("fname") String firstName,
    @RequestParam("lname")String lastName,
    @RequestParam("email")String email,
    @RequestParam("password")String password 
)
